Short answer: mining site electrical installation parts should be selected by dust, vibration, moisture, mechanical impact, cable size, grounding risk and maintenance access.
| Cable accessories | Use MV joints, terminations, lugs, cleats and glands matched to heavy-duty cable and site environment. |
|---|---|
| Protection and grounding | Include surge arresters, SPDs, ground rods, clamps, bonding conductors and inspection points. |
| Routing protection | Use tray, conduit, cable support and sealing parts where cable is exposed to impact or dust. |
| Maintenance spares | Keep spare lugs, glands, fuses, ties, clamps and transformer accessories for site repairs. |
Mining projects should not use light-duty cable fixing or sealing products where vibration and impact are high.
